What exactally is done to the engine when refering to type-r conversion, how much does it cost (ballpark) and where can i find the parts for it

 

Type-R engine is either a B18C or B16B, none of which uses a 1.6 shortblock. Both use the 1.8 shortblock.

 

b16b is still a 1.6
or else it would be called a b18b

anyways u should search because this crap has been covered many times...
y are noobs even allowed to create new topics?!?

 

 

B16 and B18 blocks are almost the same, the difference are the rods and crank shaft.

 

b16b and b18c1 = same block. Look at any b16b block i bet it says p72.

Wouldn't it be the same as ITR? I thought the CTR was a destroked ITR?

 

ctr ,gsr,itr +same block. except the itr might say p73 not sure though.

 

P72 and PR3 are head cast numbers, and will not be on the block.

I know for a fact my USDM C1 block has P72 stamped it. I saw it with my own eyes just recently

 

ya and ive seen for my own eyes a b16b block and on the bottom it was stamped p72 and it was exactly the same as a gsr block i had. Ive taken apart a itr motor before but i didnt checck and see if it said p72. it should though because its the same block as a gsr.

 

so i can take my B16A3 and stick a b18 crank and rods and it'll be a b18?

Nope, you will have a messed up head.

 

b16a and b16b are way different. when you say b16b just think of b18c1.

 

This is a funny thread. ITR and CTR's use the same engine blocks. THe diference is in their stroke distance. THe CTR's pistons travel less, thus making the engine a 1.6L.

Correct me if I am wrong but this is how I allways though things worked.

 

JDM B16a2

 

we all know that they are the same blocks we are not arguing that. Also everyone knows that they have different rod sizes.

 

B16,B16A-1,2&3 all have a shorter deck height than a B18a/b, B18c1-5 block. all just have different rods and cranks. Pretty much what everyone else just said.

 

so much wrong info

 

they should let douchebags make posts either, why dont you find the definition of a forum and get a life and not respond if you think its stupid

 

true!
but b16b with a shorter stoke and less torque

 

damn now im just confused everything i thought about the liters and block codes are ****

 

i wish i would have never read this. someone needs to clarify this butter.

 

B16b, B18c1-5 = 1.8 block regardless. only difference is stroke, and head. B16b is a ITR motor but with 1.6 internals hense B16b, and not B18.

you can't make a 1.6 into a 1.8 without changing the bore, and stroke.

 

Alright, here's my humble opinion..

First off, scratch the CTR or any branches using that motor, it costs way too much and doesn't have enough torque due to the low *** stroke, better motor IMO than the ITR for boosting....if you're not boosting, I'd say ITR &gt; CTR...but that's just me.

Now I think what you mean by "type-R conversion" is when somebody buys a B16a or GSR motor and puts ITR cam shafts, valve train, pistons & rods int here - it's also known sometimes as the "poor man's type R." It's usually done with a GSR, but I'm sure somebody's pulled it off with a 99/00 si motor.

I suppose in the name of all that's interchangable you can put CTR stuff in there instead but why pay just as much (if not more) for parts that won't up the ante on your engine as much?

Hope that helps.
